Imports Infragistics.Win.UltraWinTree
This topic will show you how to change the ActiveNode programmatically.
Before you start writing any code, you should place using/imports directives in your code-behind so you don’t need to always type out a member’s fully qualified name.
In Visual Basic:
Imports Infragistics.Win.UltraWinTree
In C#:
using Infragistics.Win.UltraWinTree;
You will need a reference to the node that you want to make active. If you know the key of the node, you can get a reference using the GetNodeByKey method of the tree.
In Visual Basic:
Private Sub Change_the_Active_Node_Load(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles MyBase.Load
Dim aNode As UltraTreeNode
aNode = Me.UltraTree1.GetNodeByKey("Add Unbound Columns to WinGrid")
End Sub
In C#:
private void Change_the_Active_Node_Load(object sender, EventArgs e)
{
UltraTreeNode aNode;
aNode = this.ultraTree1.GetNodeByKey("Add Unbound Columns to WinGrid");
}
Once you have a reference to the node, you can set the ActiveNode property of the tree to that node.
In Visual Basic:
Me.UltraTree1.ActiveNode = aNode
In C#:
this.ultraTree1.ActiveNode = aNode;
